Definition

material entity with a surfactant role

Semi-Formal Definition:

every instance of ‘surfactant’ is defined as exactly an instance of ‘material entity’ that ‘has role’ some ‘surfactant role’

Explanatory Notes

See expanded definition under the corresponding role class. The term is formalized here as a defined class by referring to its corresponding role class and exists primarily for ontological modeling and implementation convenience.

Examples

• polysorbate 80 when added to culture medium to improve wetting and dispersion; Sodium dodecyl sulfate (SDS) when added to aqueous buffer to reduce interfacial tension
